Organic milk is now widely available in most grocery stores across the country. Should you spend the extra money for milk that is certified organic? Is it more nutritious or safer than conventional milk? There is controversy surrounding the answers to these questions and depending who you talk to, organic milk is either a must buy for consumers or a waste of money. Let’s take a closer look.
According to the United States Department of Agriculture, milk can only be labeled “organic” if the cows have been fed exclusively organic feed, have not been given synthetic hormones, have not been given antibiotics, are kept in pens with adequate space, and are allowed access to the outdoors. Proponents of organic milk argue that these standards make the milk safer than conventional milk by controlling antibiotic and hormone levels in the milk. It would seem that less hormones and antibiotics given to cows would result in milk that is safer. You can find much information on the web about the improved safety of organic milk, most not supported by scientific evidence. In fact, milk—conventional and organic—is one of the most tested foods on the grocery store shelf. Studies have found no meaningful difference in hormone or antibiotic content of organic versus conventional milk.
What about nutritional composition? This is an easier one for you the consumer to check. A quick look at the nutrition label of conventional and organic milk reveal identical products with respect to vitamins, minerals, and protein. Fat content is similar based on the type of milk in question.
One difference between organic and conventional milk is price. The higher cost for farms to follow the guidelines required to be certified organic cause organic to carry a higher price tag. Another difference is that most organic milk is ultra pasteurized (heated for a longer period of time) and will last longer unopened than milk that is pasteurized using traditional methods.
Safety is similar, nutrition is similar—why then does the demand for organic milk continue to increase with an estimated 25% more certified organic cows each year since 2000? Many consumers believe, in spite of evidence to the contrary, that organic milk is a safer and more wholesome product. Consumers also may make the organic choice based on how animals that are certified organic are treated, access to pasture and less crowded conditions. Another reason to choose organic would be to support organic farming practices that are more environmentally friendly. Ultimately, the decision is up to you as to your choice of milk, organic or conventional. If cost is a factor, conventionally produced milk may be a better choice since it delivers the same nutritional punch.
